this is my json object. i need to get only all the values of packageName and assign it to an array. can any body help me with that. i can not go for using indexes since this is dynamic object.
thanks in advance.
var data = [
{
"packageName":"string",
"packageValue":"string"
},
{
"packageName":"string",
"packageValue":"string"
}
]
Use javascript map function
var packageNames = data.map(function(obj){
return obj.packageName;
})
var data=[
{
"packageName":"string1",
"packageValue":"string"
},
{
"packageName":"string2",
"packageValue":"string"
}
]
var packageNames = data.map(function(obj){
return obj.packageName;
})
console.log(packageNames)You can use filter function and add to array only when this key exists.
var arr = [];
data.filter(getValue)
function getValue(data){
if(data[packageName]){
arr.push(data[packageName])
}
}
You can add an if statement to check the key and then push it to an array.
for(var i = 0; i< data.length; i++){
for (var property in data[i]) {
if (data[i].hasOwnProperty(property)) {
console.log(property);
console.log(data[i][property]);
}
}
}
